Implementation tips that save time (and headaches)
- Start with the job, not the test. Define success outcomes—ramp time, quota attainment, CSAT, error rates—and choose assessments that predict those outcomes. This ensures your cut scores are anchored to the work
- Pilot before scaling. Run a 30–60 day pilot with current employees in the role to validate score thresholds and flag adverse impact. Adjust your battery and timing (e.g., screen early with short tests, reserve longer tasks for finalists).
- Track downstream KPIs. Tie assessment data to performance, retention, and promotion rates. Over 2–3 quarters you’ll know exactly which measures predict on-the-job success—and which you can safely retire.
- Protect candidate experience. Keep assessments relevant, concise, and mobile-friendly. Communicate what you’re measuring and why. Send quick feedback where possible to leave a positive brand impression.
The Bottom Line
